Do I need planning permission in Spain for a pool, a patio or a new concrete slab? It is one of the first questions British and other foreign owners ask, usually after hearing three different answers from three different neighbours. The honest reply is that it depends on the work and on your town hall, but the system itself is easy to understand once you know the Spanish terms. This guide explains them in plain English.
Short answer: In Spain, almost all building work needs some form of permission from the ayuntamiento (town hall). Smaller jobs are usually handled as obra menor, often through a simple declaración responsable, while a new pool or larger structure is usually obra mayor with a licencia and technical project. The rules differ by municipality, so always check with your own ayuntamiento before work starts.
Do I need planning permission in Spain for building work?
Yes, in Spain nearly all building work needs some form of town hall approval, even when the job seems small.
Planning in Spain is mostly handled locally. Each ayuntamiento applies the regional planning law of the Valencian Community and its own local plan and bylaws. That is why the answer can differ between Altea and Jávea, or even between two zones of the same municipality.
What changes from job to job is not if you need permission, but which kind. The town hall's urbanismo department, or your architect or builder, can tell you which route applies to your plot and your project.
Obra menor and obra mayor: the two main categories
Spanish building work is usually split into obra menor (minor works) and obra mayor (major works), and the category decides the paperwork.
Obra menor generally covers simple jobs that don't touch the structure: replacing floor tiles, repairing a wall, laying a small patio, some garden works. These usually need only a short application or notification, without a full architect's project.
Obra mayor generally covers new construction, extensions, structural changes and works that change the volume or use of a building. In many municipalities a new swimming pool falls in this group. Obra mayor usually needs a technical project signed by an arquitecto, a licencia de obra and a technical director on site.
Where exactly the line falls is set by each town hall. A job that is obra menor in one ayuntamiento can need more paperwork in the next.
Declaración responsable or licencia: what is the difference?
A declaración responsable is a signed statement that lets many minor works start without waiting for approval, while a licencia is a permit the town hall grants before work begins.
With a declaración responsable, you or your builder declare that the work meets the rules and submit the required documents. In many cases the work can then start, and the town hall checks afterwards. It is quick, but the responsibility is yours: if the work turns out not to qualify, it can be stopped.
A licencia de obra is a formal permit. The town hall reviews the project and grants or refuses it. This takes longer and usually applies to obra mayor. Fees and the construction tax known as ICIO are set by the town hall. The ayuntamiento can tell you what applies and how long it usually takes.
Operator's tip: Ask your builder for a copy of the permit or the stamped declaración responsable before the pour is booked. It is the simplest way to make sure nobody stops the job halfway with concrete in the drum.
Do I need planning permission in Spain for a swimming pool?
For a new swimming pool in Spain you usually need permission, and in many municipalities it is treated as obra mayor with an architect's project.
A pool involves excavation, a reinforced concrete structure and connections for water and electricity. That is why many ayuntamientos ask for a project, a licencia and a technical director. Some treat small or prefabricated pools differently. Your town hall decides.
A new pool is also normally something to register with the Catastro, as it can change the cadastral value of the property. Your architect or gestor can advise on that. For the building side, read our guide on building a concrete pool in Spain and our page on concrete for swimming pools. One of our real jobs was 18 m³ for a pool in Alicante.
Patios, driveways, slabs and garden walls
Patios, driveways and slabs are often obra menor, but size, location and what sits underneath can change that.
A new patio in the garden, a driveway or a base for a shed is usually seen as minor work. It can become more complex when the slab is large, when it raises ground levels, when it is close to a boundary or when it supports a structure such as a pergola, carport or outbuilding. Garden walls and retaining walls on sloping plots often have their own rules on height and position.
For the technical side, our guide on how thick a concrete slab should be and our page on concrete driveways and patios help. Decorative finishes such as stamped concrete follow the same planning logic as any other slab.
Typical routes by type of work
As a rough guide, small surface works go through a simple notification and structural or new work through a licence, but your town hall has the final say.
| Type of work | Usual category | Usual paperwork |
|---|---|---|
| Re-laying an existing patio | Obra menor | Often a declaración responsable |
| New patio or driveway slab | Often obra menor | Declaración responsable or simple application |
| Liquid screed in an existing house | Usually obra menor | Depends on the wider renovation |
| New swimming pool | Often obra mayor | Project, licencia, technical director |
| Extension or new house foundations | Obra mayor | Project, licencia, technical director |
| Retaining wall on a slope | Varies | Ask the ayuntamiento |
Treat this table as a starting point for the conversation with your town hall, not as an answer.
How to check and apply, step by step
The safest route is to ask the ayuntamiento early, let a professional prepare the paperwork and only book the work once it is approved or submitted.
- Describe the job: what, where on the plot, size, and any structural parts.
- Ask the urbanismo department, or your arquitecto or aparejador, which route applies.
- Have the documents prepared: drawings, budget, and for obra mayor a technical project.
- Submit the application or declaración responsable and pay the fees the town hall sets.
- Keep the stamped copy or licence on site.
- Book the builder, the pump and the concrete.
Things get more complex on rustic land, near the coast or in protected old town centres. If your plot falls in one of those, get professional advice before you plan anything.
Permission for the pump on the street
When a pump and mixer lorry have to stand on a public road, some town halls want a short application to occupy the road.
This is separate from the building permit. On a quiet urbanisation lane it is often not an issue; in a busy old centre the policía local may need to know. Our article on concrete pumping with narrow access covers setting up on tight streets, and our narrow access concrete pump keeps the footprint small.
The permit itself is for the owner, the builder and their architect to sort out. Our part is the pumping: once the paperwork is in order, we coordinate the date with your builder and the plant, in English or Spanish. Our concrete pour checklist helps you prepare.
Booking the pour once the paperwork is done
Once your permit is in place, a pour can usually be scheduled within three working days.
We give you one fixed price for the pump, operator, lines, setting up and cleaning up, with the concrete on the same quote. Our page on what concrete pump prices depend on explains the factors, and our concrete pump hire with operator page shows the set-up. Builders running several projects can read about our concrete pumping for builders. To get a price, request a quote or send photos on WhatsApp to +34 633 361 962.
Frequently asked questions
Do I need a licence to build a pool in Spain?
Usually yes. Many ayuntamientos treat a new pool as obra mayor, with an architect's project and a licencia de obra. Check with your town hall.
Do I need permission to lay a concrete patio in Spain?
Usually some form of permission, often as obra menor through a declaración responsable. Larger slabs or slabs that support a structure can need more.
What is a declaración responsable?
A signed statement that your work meets the rules, submitted with the required documents. For many minor works it lets you start without waiting for formal approval.
What is the difference between obra menor and obra mayor?
Obra menor is minor work that doesn't affect the structure. Obra mayor covers new construction, extensions and structural work, and usually needs a project and licence.
Who applies for the building permit?
The owner applies, usually with help from the architect, builder or a gestor. The ayuntamiento tells you which documents are needed.
